The 22-year-old Shields, the USA's only two-time Olympic boxing gold medalist, male or female, won all 10 rounds on each of the three judges' scorecards. Shields connected on 186 of 425 power punches, while Nelson, who came in with a reputation of being an aggressive fighter, landed just 70 of 348 (20%).

"As far as fighting me, I think she's pretty scared, to be honest", Shields said. "It's a great combination me and her on the same card", she said.

"I landed every shot that I thought possible to land". "She's more anxious about me than I am her". A lot of times, when I did see shots open and I went for them, I got head-butted. "And I'm gonna kick Hammer's ass". "I can't wait to fight her and show her that she isn't (better than me)".

Shields tried her best to get a knockout in the 10th round, but wasn't able to hurt Nelson with any of her punches.

Nelson was in survival mode by the sixth round and Shields told trainer Jason Crutchfield heading to the seventh that Nelson was "getting weaker".

WBAN has just posted pre-fight interviews and footage of the upcoming fight tonight between Shields vs. Nelson. Shields drilled Nelson with a flush right hand to the jaw when there were about 25 seconds to go in the fifth. She recorded a unanimous eight-round decision over Sydney LeBlanc last June at Detroit's Masonic Temple.

But Shields will have to defend her titles for the first time against Tori Nelson, a 41-year-old competitor from Ashburn, Virginia.

Germany's Hammer (22-0, 10 KOs, 1 NC) was supposed to fight on the undercard Friday night, but watched the action from ringside.
